If you're referring to the VTC training CDs, I liked them and thought they were worth the price. I'm one of those people who needs to see how something is done in order to make sense of what was written in the manual (I also found the Friendly Spider CDs helpful for Amapi). They cover a large range of topics, but they won't turn you into an expert. I'm happy I got them and refer to them when I'm stumped about something.
